Databricks Certified Data Engineer - Associate

Explanation

The correct answer is B because:

1. Requirement: The data engineer needs to run a new notebook prior to the original task. This means the new task should execute first, followed by the original task.

2. Task Dependencies in Databricks Jobs: In Databricks, you can set up task dependencies where one task must complete before another starts. When you add a task as a dependency of another task, the dependent task will wait for the upstream task to complete.

3. Option B Analysis: "They can create a new task in the existing Job and then add it as a dependency of the original task." This means:

   • Create a new task for the new notebook
   • Make this new task a dependency of the original task
   • Result: New task runs first → Original task runs after new task completes

4. Why other options are incorrect:

   • A: Cloning the existing task doesn't create a proper dependency chain
   • C: This would make the original task run first (opposite of what's needed)
   • D: Creating a new job from scratch is unnecessary and doesn't maintain the existing scheduling
   • E: Cloning to a new job creates separate jobs without proper coordination

5. Best Practice: Adding tasks with dependencies in the same job maintains the existing scheduling configuration and ensures proper execution order.
